Regulatory Framework: Federal (NESHAP, OSHA, AHERA) and Pennsylvania Requirements
What this domain tests
This domain tests jurisdiction: which law controls emissions, which controls worker exposure, which controls schools, and what Pennsylvania adds. Many questions give a scenario and ask which rule or notification applies.
Core rules and concepts
- NESHAP, 40 CFR 61 Subpart M, controls asbestos emissions from renovation and demolition. It defines ACM as material containing more than 1% asbestos by weight. Regulated ACM (RACM) includes friable ACM and nonfriable ACM that will be disturbed so it may become friable. Notification is generally required 10 working days before starting when thresholds are met or for demolition.
- OSHA, 29 CFR 1926.1101, protects construction workers. It sets a 0.1 f/cc 8-hour TWA PEL and 1.0 f/cc 30-minute excursion limit, defines Class I–IV work, and requires a competent person, exposure monitoring, respiratory protection, medical surveillance, and regulated areas.
- AHERA, 40 CFR 763, applies to K–12 school buildings. It requires accredited inspectors and management planners, a management plan, 3-year reinspections, 6-month surveillance, and clearance at 0.01 f/cc under aggressive sampling.
- Pennsylvania requires state certification under its asbestos occupations law and DEP notification for abatement projects. PA work-practice and training requirements can be stricter than the federal minimum, so holding an OSHA certificate alone does not authorize abatement work in PA.
Worked example
A PA school plans to remove 200 square feet of floor tile. AHERA applies because it is a school; the management plan must be consulted and accredited persons used. NESHAP notification is triggered because the removal exceeds the 160-square-foot threshold for facility components. OSHA applies to the employees doing the removal. PA certification is required for the workers and supervisor. The tile is Category I nonfriable, but cutting or grinding could make it RACM, so wet methods and careful removal matter.
Traps that cost marks
AHERA does not replace NESHAP or OSHA. "10 working days" is not 10 calendar days. The 1% definition is not an "any detectable asbestos" rule. Do not assume nonfriable material is outside NESHAP if it will be broken.
